New iScan Functions: Impression Scan & High Resolution Scan

Share this with a friend:


Have you been trying out the new functions in iScan? In this blog article, we’ll be sharing tips on how to make the most of two of these updates, namely the impression scan and high resolution scan functions. Read on to find out more.


Impression Scan Function


The impression scan function allows you to seamlessly overlay data acquired by scanning the patient's teeth with data collected by scanning a traditional impression. This integrated scanning process can be used for the whole jaw or a spot area.


You might be wondering why you need to scan impressions when the point of using an intraoral scanner is to go digital and do away with the need for traditional impressions. While this is true for most cases, there are considerable benefits of this function in certain situations.


In some cases where, for example, the patient is bleeding too much, being able to combine the intraoral scan with the impression scan will allow you to get more accurate results.


Additionally, in cases where an area is too deep and narrow to scan, like in some Post & Core cases, using the impression scan function will allow you to acquire the necessary data easily. This function is also useful in occlusion alignment.



High Resolution Scan Function


The high resolution scan function enables the scanner to capture images in high-resolution for an entire jaw or a partial area. However, that does not mean that you should start scanning everything in high resolution. Doing so will slow down post-processing and result in a much bigger file size which is why we discourage scanning an entire jaw in high resolution unless absolutely necessary.


The standard resolution is usually sufficient to get the data that you need for most cases. However, the high resolution option is useful for when you need to get a lot more data of a particular spot area, especially when scanning prepared teeth or certain scanbodies which require more intricate details. You can easily enable and disable the high resolution mode throughout the scanning process by double pressing the button on the scanner or clicking the icon on the desktop.


There’s no need to worry about discrepancies in the scan data when you scan in both high resolution and standard resolution as iScan will merge both data during post-processing for smooth results.
